Turning and tossing

I got drunk tonight, tried to drown my pain,
Sleep was to be my drug, but I drank in vain.
I closed my eyes for an hour, the last bottle in my hand,
But woke up now, unable to cut this band.

I saw you in my dreams, screening sand,
My little angel, so innocent and pure,
Unaware of the distress you were to endure.

I have a hangover, yet I am completely numb.
Amenable to charge, I was dumb.
Nemesis spoke a severe sentence, but I should accept.
I feel guilty, because you are dead.
